Northwest Midfield Terminal
Project: Northwest Midfield Terminal
NSC used an innovative erecting technique to put the roof into place on the terminal. The soaring design of the new one mile-long, two-million-square-foot airport terminal with high arched ceilings, open spaces and large gate areas, inspired the remarkably resourceful approach to raising the roof into position.
A large percentage of the steel for the roof was ground-assembled in eight-bay segments. Once NSC completed the structural steel components, follow-on trades had a 20-day window to install the finished systems. Then, using an engineering lifting system comprised of 16 jacks, one on each side of the bay segments, stationed on top of the columns, the entire roof was elevated at once.
